Description

Profile for frames of fitness and health equipment

The invention relates to a profile for frames of fitness and health devices.

Fitness equipment is used for training athletes, health equipment for the rehabilitation of patients. The various fitness and health devices are moved standing, lying or sitting, depending on the design. A special device is preferably provided for each muscle group. The designation of the devices is based partly on the trained muscles, partly on moving parts of the body, partly on the type of movement.

With a few exceptions, the movement in the known devices is countered by means of weights that can be raised and lowered. The lifting and lowering weights are guide devices or arranged in a frame. The preferred form of the guide device is formed by guide rods which are held in the frame and on which the weights slide.

The weights are moved using traction devices. Ropes, chains and tapes serve as traction devices. The traction devices connect the weights to moving machine parts or are "directly operated by hand.

The exercises then run against the resistance of the weights. Usually there are weight packets that can be coupled with the traction device, so that the resistance can be adjusted by changing the number of weights.

In the following, the frame parts with the lifting and lowering weights are referred to as weight frames. The weight frame doors can be found in various fitness and health machines as a machine component or machine frame. Known machines include:

Abdominal machines

Back extension machines

Seithebe machines

Shoulder machines

Biceps machines

Triceps machines

Bankdriick machines

Kick-machines

Leg Extension Machine

Hamstrings machines

Calves machines

Leg Press Machine

Adduction Maschenen

Incline machines

Coating machines

Butterfly machines

Neck push machines

Rowing machines

Back Machines

Twister machines

Cable pulley stations

double stations

Wade machines

Klimmzugmaschine

Barren machine According to a known proposal, the weight frames have connection surfaces at the top for a crossbar and, if appropriate, for a head plate as the upper connecting element

The crossbeam serves to form the distance for the cable pull station and the head plate as a stable connection when used for the double station. The complement each other

Head plate and the upper connecting surfaces of the weight frame in an ideal way.

Preferably, the crossbar is provided with a connecting flange, which is the top of the

Weight frame completely or partially covered, so that the same connection as in the

Headstock is possible.

At the bottom, the weight frames are optionally provided with a U-shaped or a T-shaped or T-shaped foot.

In addition, a screw connection is also known below when using a lower traverse.

This not only results in rationalization advantages in manufacturing and storage, but also transport advantages. The transport volume can be achieved by merging the

Machines can be drastically reduced. In addition, the devices are much easier to handle during transport.

The weight frames are part of the devices.

Other components are, for example, swiveling levers, seats, backrests.

The levers, seats and backrests require storage and mounting. It is held by the machine frame or device frame. The weight frame can go through

Connection with the parts forming the bracket to the machine frame.

At least the weight frame complements the machine frame.

The known weight frames usually consist of a hollow profile.

Profiles with a rectangular cross section are predominantly used, rarely

Profiles with a round cross-section or oval cross-section. The rectangular profiles are more complicated to manufacture than a round profile, and also more complicated than the manufacture of

Profiles with oval cross sections, which are preferably created by upsetting round profiles.

However, there are considerable advantages in the use of rectangular profiles. The

Advantages lie in the connections of the profiles, especially in the joints between struts and supports. This is especially the case when profiles with different size dimensions need to be pushed. Against this background, profiles with a rectangular cross section are currently used almost exclusively.

As explained above, the profiles have proven themselves.

Nevertheless, the invention has set itself the task of improving the profiles.

The invention turns to an elliptical profile cross section, which has an extremely high application effort compared to rectangular profile cross sections.

In addition, an elliptical profile involves considerable manufacturing effort because it is a special profile, while rectangular and round profiles in contrast

Standard profiles are. The production of special profiles requires special rollers and special welding processes. Nevertheless, the invention chose this profile because it has much lower strength values than the conventional profiles.

The meaning of the strength values is not immediately apparent because the conventional profiles are usually oversized.

However, the invention has recognized that it is not only a question of strength against breakage or permanent deformation. The invention has recognized that the vibration of the machine affects the user. The more vibration-resistant the construction, the greater the user's feeling of comfort. In itself it would be obvious, after knowing the

Relationship between comfort and vibration resistance through additional

Support or struts to stiffen the machine frame or implement frame. The invention nevertheless takes a different approach, changing the cross section of the general profiles of the machine frame. Surprisingly, the additional effort is much more bearable than expected.

According to the invention, profiles with the cross-section of an ellipse and more preferably with the following dimensions are preferably used for supports and struts of the machine frame: 150 mm (largest external dimension) to 75 mm (smallest external dimension) or 120 mm to 60 mm or 100 mm to 50 mm or 80 mm to 40 mm or 60 mm to 30mm. A distinction must be made between the dimensional tolerances and other nominal dimensions. The dimensional tolerances are at most equal to the possible thickness of a weld seam when welding profiles, the dimensional tolerance is preferably at most 4 mm, more preferably at most 3 mm.

In other dimensions, the nominal dimensions deviate at most by 10%, preferably at most by 5%, from the nominal dimensions / external dimensions given above. The wall thickness of the tubes according to the invention is preferably at most 6mm, even more preferably 5mm and most preferably 4mm.

The pipe joints come in different forms. The invention distinguishes between the joints of tubular profiles of the same dimensions and the joints of

Pipe profiles of different dimensions.

In the case of joints of pipe profiles of unequal dimensions, preferably between three

Basic patterns and modifications are distinguished from these basic patterns. The

Basic patterns are based on a continuous larger profile and a smaller profile following the continuous larger profile.

A profile is not only continuous if it protrudes significantly from the standing profile. Continuous in the sense of the invention is a profile when it covers the entire end face of the standing profile.

The position of the smaller profiles on the larger profile is determined by the longitudinal axis of the profiles, by the position of the narrow side and by the position of the broad side. In the following, the broad side is the side view of the profile, in which the profile shows the largest external dimension. In the following, the narrow side is the side view of the profile, in which the profile shows the smallest external dimension.

In all basic designs, the smaller profile is perpendicular to the outer jacket of the larger profile.

With basic patterns A and B, the smaller profile is centered on the broad side of the larger profile. With basic pattern A, the broad side of the smaller profile runs exactly 90 degrees transverse to the longitudinal axis of the larger profile when projected onto the broad side of the larger profile. In the basic pattern B, the broad side of the smaller profile runs exactly parallel or in alignment with the long axis of the larger profile in the projection onto the broad side of the larger profile.

In the basic pattern C, the smaller profile is centered on the narrow side of the larger profile and the narrow side of the smaller profile in the projection on the narrow side of the larger profile is exactly parallel or flush with the longitudinal axis of the larger profile. The outer dimension of the smaller profile is preferably smaller than the narrow side of the larger profile.

In the variations of the basic pattern, the angular position of the smaller profile to the larger profile can vary. This applies both to the circumferential angle of the larger profile and to the angle to the plane in which the broad side or the narrow side of the larger profile lies.

The joints according to the invention can be produced in that a hole with the contour of the smaller profile is made in the larger profile. The contour can be easily produced with an EDP-controlled milling cutter.

Alternatively, the end face / contact surface of the smaller profile can be adapted to the respective curvature of the contact surface of the larger profile. The adjustment can be done as above with the help of an EDP-controlled router. As a result of the adaptation, the smaller profile can be brought into contact there without damaging the outer surface of the larger profile, without a gap being formed, the opening width of which is greater than the permissible dimension for welding. The opening width for normal weld seams is at most 75% of the normal weld seam width, preferably at most 50% and even more preferably at most 25% of the normal weld seam width. The normal weld seam width is the usual weld seam width with adjacent surfaces of larger and smaller profiles. The usual weld seam width is preferably a standardized weld seam width, even more preferably DIN weld seam widths.

In special cases, the opening width of the gap between the larger and smaller profiles, even with a straight end face of the smaller profile, is small enough to produce a desired weld connection with a conventional weld. This is the case with larger dimensional differences between the tubes and especially when the smaller profile stands on the broad side of the larger profile.

Larger opening gaps can also be closed when welding, if the material edges are welded together with a build-up weld until they are welded with a last weld can be closed. The build-up welding can be carried out continuously around the edges of the material or back and forth at individual edge points. A welding operation in smaller and / or larger steps is possible in which a connection between the material edges is produced by welding back and forth.

The procedure according to the invention includes that with larger dimensional differences between the outer dimensions of the profiles, straight end cuts are also used for the connection surfaces of the smaller profiles. The resulting gaps can be bridged with simple weld seams.

There are larger dimensional differences if the resulting gaps between the smaller profile and the larger profile lie in the frame described above.

Gaps can also arise in the case of a straight forehead cut on the profiles in that the profiles stand on the supports at an angle that deviates from 90 degrees when connecting to a frame with inclined supports as trusses.

In addition to the connections of different profiles, connections of the same profiles can also be considered. The basic patterns A to C described above can be used to connect the same profiles. However, according to the invention in all modifications it is provided that the profile standing on the continuous profile does not project laterally beyond the edge of the continuous profile. The continuous profile can assume different rotational positions A angular positions compared to the standing profile. Likewise, the standing profile can assume different rotational positions / angular positions compared to the continuous profile compared to the continuous profile. As far as the condition of the non-protruding edge is met, the same situation arises as described above for the different profiles.

When connecting the same profiles, there are also joints between pipe ends. The central axes running through the narrow sides or the central axes running through the broad sides have both profiles parallel to one another. Miter cuts are provided at the joints. In one situation, there is freedom of choice between the miter cut and handling as a continuous profile with one standing profile. This situation exists when one profile covers the entire end face of the standing profile and does not go beyond it.

Preferably not only the weight frame consists of the new profile, but also other machine parts. That is in particular

Supports and struts for fixed or woven seats, backrests, loungers and

Supports and struts for the storage of levers and movable levers and other moving machine parts and

Supports and struts for stabilizing the machine frame and

Supports and struts for the fixed arrangement of handles and

Supports and struts for fixed and movable contact surfaces and

Machine feet and device feet

Both the connection of the supports and struts and feet requires connections of the same and different profiles, as described above.

The connection of profiles also occurs when angling supports or struts or levers or feet. That applies, for example, to

leg plug

Glutaeusmaschinen

Back extension machine

Coating machinery

Bench press machine

Klimmzugmaschinen

Abduktionsmaschinen

Shoulder machines The bending is then carried out by separating at the intended bending point and reconnecting after preparation of the profile ends. The ends of the profile are mitred so that a welded joint can then be made.

Instead of bending through separation and reconnection, bending through can also be used. Bend.

The bending is preferably carried out with jaws between which the profile is clamped and which are then pivoted against each other. During the bending, the profile is preferably only bent such that the deformation resulting from the bending at the bending point leads to strength values which are at most 25% less than the strength of a welded joint described above, and preferably equal to or better than the strength of a welded joint described above Welded joint is.

The quality of the deformation is largely determined by the bending radius and the extent to which the bending axis runs parallel to the flat side of the profile (flat is bent) or parallel to the narrow side of the profile (edgewise is bent) and how far the bend runs and how thick the profile wall is ,

If a profile with a wall thickness of 3 to 5 mm is bent flat up to 90 degrees, the mean bending radius is at least equal to the largest external profile dimension, preferably at least equal to 1.25 times the largest external profile dimension and even more preferably at least 1.5 times the external dimension large profile outside dimension. In the case of a profile with a largest external dimension of 120 mm, this results in at least a mean bending radius of 120 mm, preferably a mean bending radius of at least 150 mm and even more preferably a mean bending radius of at least 180 mm when a 90 degree angle is bent. The bending radius at the center line of the profile is the middle bending radius.

If a profile with a wall thickness of 3 to 5 mm is bent upright up to 90 degrees, the mean bending radius is at least equal to 3 times the largest external profile dimension, preferably at least 3.5 times the largest external profile dimension and even more preferably at least 4 times of the large profile outer dimension. With a profile with a maximum external dimension of 120, the result is as a result, with a bend of a 90 degree angle, an average bending radius of at least 360 mm, preferably an average bending radius of at least 420 mm and even more preferably of at least 480 mm. The bending radius at the center line of the profile is the mean bending radius.

In the drawing, a weight frame according to the invention is shown in its application.

1 and 2, the different weight frames consist of two inclined supports 1 and 2, which are connected at the top by a Kopφlatte 4 and below by a crossbar 3. According to FIG. 2, the supports 1 and 2 consist of a hollow profile 10 with an elliptical cross section with characteristic diameters of 75 mm and 150 mm. In other exemplary embodiments, the diameter is at least 80 mm, preferably at least 120 mm at the largest point. The column height is at least 1200 mm, preferably 1500 mm or 2000 mm. The inclination of the supports 1 and 2 is 1 to 4 degrees, preferably 2.6 to 3 degrees to the vertical.

The cross member 3 is also formed by an elliptical profile, preferably by the same profile as in the supports. The support profiles and the cross-member profiles are preferably arranged in such a way that the longitudinal sides of the supports are aligned with one another. The long sides also form the flat sides / broad sides on the profile. In the arrangement provided, two flat sides of the supports 1 and 2 face each other. The inner traverse is arranged so that a narrow side of the elliptical profile is on top. The long side is upright.

The joint between the cross member 3 and the support 2 is shown in FIGS. 3 and 4 and corresponds to the basic pattern B explained above. The external dimensions of the support 2 are designated H2 and B2, the external dimensions of the cross member 3 with Hl and B1. It can be seen that the crossmember 3 is adapted to the contour of the support 2 on the contact surface. This was done by form milling. In the exemplary embodiment, Hl is H2 and B1 is B2.

In other exemplary embodiments, Hl is less than H2 and Bl is less than B2. The latter is shown in FIGS. 5 and 6 using an impact. There is also a different location there Traverse 3 'shown. The broad side of the cross member 3 'runs exactly 90 degrees transverse to the longitudinal axis of the support 2, the cross member 3' standing on the broad side of the support 2. This corresponds to basic pattern A described above.

In the embodiment, the Kopφlatte has a thickness of 10mm.

In addition, the Kopφlatte 4 at the lateral ends at which the Kopφlatte 4 with the

Supports 1 and 2 are connected, rounded. The rounding on the outer edge corresponds to

Kopφlatte 4 of the rounding there on the supports 1 and 2.

In the exemplary embodiment, the top plate 4 has an elliptical shape.

In other embodiments, the Kopφlatte still has an attachment and / or another

Shape. The attachment is adapted to the contour of the head plate and creates a central

Thickening of the Kopφlatte. The thickening has a dimension of up to 60mm, preferably up to 50mm, based on a Kopφlattenlänge of at least 500mm, preferably at least

6O0mm.

Another form of the Kopφlatte results in particular when several roles on the

Kopφlatte for guiding the traction means up to the weights are provided. For this purpose, a spreading of the plate relative to the elliptical shape is provided in particular.

An attachment 25 for a widened Kopφlatte is shown in FIGS. 9 to 11. 10 shows a plan view with two fastening holes 26. These holes are located in one

Kopφlatte without widening in the center of the attachment. Through the widespread rank is in the

10 a larger edge distance was created on one side. The widening of the Kopφlatte serves to attach additional roles to redirect the traction to the lifting and lowering weights.

Fig. 9 is a front view, Fig. 11 is a side view. In the exemplary embodiment, the two views show that the attachment thickens from the edge to the middle, the greatest thickness being 50 mm with an attachment length of approximately 600 mm.

1 weights 5 are arranged to be raised and lowered. The weights 5 are added to rods 6 in the enclosed frame. The traction means are ropes, chains, tapes that are guided to the weights via rollers 8 and 9. The rollers 8 and 9 are arranged on the Kopφlatte and the crossbar. In the exemplary embodiment, the weight frames are intended to be equipped with a swivel lever. For this purpose, a bearing 7 made of a sleeve or a tube is provided on the inside. About half of the tube is embedded in the support 1.

Parts 1, 2, 3, 4 and 7 are welded together.

In the exemplary embodiment, the swivel lever is moved by the practitioner with the lower leg. The practitioner sits on a firm seat. Such exercises come with the

Leg bends or leg extensions.

7 and 8 show an abutment of a support 20 with a crossmember 21 corresponding to the basic pattern C described above. The crossmember 21 is centered on the narrow side of the support 20. At the same time, the broad side of the crossmember 21 runs parallel or in alignment with the longitudinal axis of the Support 20. The outer dimensions Hl and Bl of the travers 21 are smaller than the outer dimensions H2 and B2 of the support 20.
